Abstract

The ancestral canal of Oued Righ at 150 km evacuates leachate water into the Chott Melghir, which has 50 oases. Excess water from discharges of sewage and drainage causes upwelling of groundwater that leads to an imbalance in the valley. The physico-chemical analysis of canal waters and water table has shown that the quality of these waters has very high salinity (class C5), with electrical conductivity of 26.30 ms/cm, and SAR> 28 (S4 class). Water hardness, the values of organic matter (O.M) and total solids (T.S) are very important. Thus, canal water has very poor quality, charged with mineral salts, and is a brackish water containing sodium chloride facies.

Key words: Canal, degradation, water, palm, water table, sol, Oued Righ.
